Designed for the production of very precise micro springs and
coils, Kine-Coil Division/Kinefac® Corporation’s Micro-Coiler and
Kine-Coiler coiling machines cover wire ranges of 0.025mm to
0.152mm and 0.127mm to 0.45mm, respectively. To provide for
total precision control, both machines are equipped with 4 axis
CNC controls.
The demonstration coil illustrates the versatility and variety of
diameters, pitches and configurations that can be programmed
using the Kinefac proprietary developed software. This coil is
made complete with no subsequent trimming required.
Tool adjustments for making coils with continuously variable
pitches and diameters can be programmed easily, and can occur
independently or simultaneously.
Typically, transitions in the opening and closing of pitches and
changing of diameters can be made within one to two coil turns.
The cuts on the round wire and flat wire coils are perpendicular
to the coil wire axis thereby eliminating sharp slivered ends
typical of manually cut coils.
The Micro-Coiler is capable of producing coils as small as
0.177mm outside diameters using materials such as 304V
stainless steel, platinum alloys or tungsten alloys.
These coils are used primarily in medical devices but also
have applications in electronic, automotive and aerospace
components.
Kine-Coil Division/Kinefac Corporation supplies the basic
micro-coiling machines as well as on demand and specialised
coiling systems. It also offers technical services including
coil design, prototyping of coils in its coiling laboratory,
micro-coiling tools, and output support systems for various
length coils.
